摘要
简述了并网光伏电站发电原理与接入系统原则;介绍了国家标准规定对光伏电站电能质量要求;以某一地市农业大棚光伏电站接入方案为例,计算分析了接入后电网对电压波动、谐波、三相不平衡度等电能质量指标的影响并提出建议。
The power generation and access system principle of grid connected photovohaic plant is described; besides ,power quality requirements for photovohaic plant according to national standard are introduced;access scheme of photovohaic plant in agriculture greenhouse in a certain city is used as an example so as to calculate and analyze the influence of power network on power quality index such as voltage fluctuation, harmonic and three-phase unbalance factor after access and make suggestions.
